This idea seems quazi illegal.... but would it work?

My question is concerning my tax refund.

Recently married, I make around 120k a year and my wife does not have a job and is a stay at home wife. 

She has 60k in student loan debt, and i have none. 

If we file jointly obviously i would recieve a tremendous refund back due to the fact i have my w2s as single 0s. And she shows no earned income... (would be like both of us made 60k before deductions)  But i would hate to have all the extra "savings" money go to uncle sam. 

 

My question is.... what is stoping me from changing my w2 to married 9 and get it in my check by calculating the lets say 10k refund (10k÷52 weeks and make sure that amount is additional in my check)  and offsetting the calculated refund to end up being 0, thus indirectly blocking the garnishment?
